Product Description

Any time you alter the height of your ride, as you do when you install lowering springs (like Steeda Sport Springs), you upset the steering geometry. You can easily bring your front end back into spec with a set of Steeda X2 ball joints. Restore roll center geometry and lower you car's center of gravity.

APPLICATION INFORMATION
PN: ST-5558101 fits 1994-2004 Mustangs. It also fits 87-93 Mustangs that are equipped with the Ford Racing M-2300-K Cobra Brake conversion kit or Baer 13" or 12" American Sedan Brake kits. It will not work with stock 87-93 brakes because of interference between the rotor and the repositioned control arm.

Steeda bump-steer kit, is highly recommended to prevent bump-steer whenever caster-camber plates are used in combination with the X2 balljoint.

TECHNICAL ANALYSIS
When a Mustang is lowered, the front roll center changes due to the new position of the suspension pivot points. Lower the car too much and the front roll center drops to well below ground level, and worse than that,the roll center moves side to side as the body rolls, resulting in lost gripand erratic handling. The lower roll center causes the body to roll more easily.

Countering this tendency usually requires a significant increase in front spring rate to simply control the added roll due to the lowered the rollcenter. This higher spring rate not only hurts ride quality, but it also reduces grip on rough surfaces, as the stiffer springs cause the tire to skip over bumps instead of following the contours of the road. The X2 balljointwas designed to eliminate these problems by correcting the front rollcenter geometry.

The X2 balljoint has a longer shaft, to raise the spindle relative to the balljoint pivot point. Spacers for the springs are included in the X2 kit to maintain the same ride height as a stock balljoint, but with a much improved roll center height. With the roll center restored to the proper height, smaller front swaybars and softer springs can be used. The result is a suspension that works for you to accommodate the small and large imperfections that are in any road or track, allowing the tires to stay planted on the ground where they belong.

CONSTRUCTION
The balljoints are made in the USA to Steeda's specifications by a respected name-brand supplier to Ford, GM and Daimler Chrysler. Except for their custom length, they are the same materials and construction that has been extensively tested in Panther applications, that is, police cars and other severe duty applications, where they have demonstrated durability that exceeds current production "regular" balljoints. They meet Ford's standards for friction, wear, and durability.

IMPORTANT DETAILS
Because the balljoint changes the relationship between the lower control arm and the tie-rod, bump-steer should be checked whenever the X2 balljoint is installed. With stock caster settings, offset rack bushings are often enough to keep bump-steer within acceptable range. However, when caster is increased, the rear inclination of the spindle further raises the steering arm where the tie-rod attaches. Therefore, an adjustable tie rod end, commonly called a "bump-steer kit", is highly recommended to prevent bump-steer whenever caster camber plates are used in combination with the X2 balljoint.

Had these installed by a professional shop. Left the spacers out and it dropped the front end an additional 1/2 inch which gave it an amazing stance with my lowering springs! Steering is much more responsive and ride is a little less bouncy up front. These are a Must if your Stang is lowered!

A very nice Steeda product and a valuable part for lowered cars. Easy to install especially if you have an air compressor handy. Costs about the same as OEM type ball joints.

GREASE THEM

I bought these with the Steeda bumpsteer kit because I recently put on the Eibach Sport system and CC Plates on my 2000 Mustang GT. The install wasn't too bad with a ball joint extractor kit rented from Auto Zone, although putting the right fittings together for that was kind of a puzzle at first. I had read on a couple of different sites that these ball joints came pre-greased from Steeda, so I did not load with grease. As soon as I took off, I heard the popping of an ungreased ball joint. I greased them and the popping stopped. They dropped the car about a 1/2". Hope they last me another 16 years!

Great addition to any lowered Mustang

I purchased a 95 GT that was lowered with only springs and drove it this way for a few weeks. I installed these X2 ball joint's without the spacer to allow for the extra 1/2" of lowering, Steeda Bump steer, caster/camber plates, poly bushings, off set rack bushings, and pretty much everything else you can think of in the suspension. What can I say, snow ball effect. The result's are amazing. It has the stability of a brand new car, instead of steering itself all over the road like it was when I got it. They are well worth the investment.

Excellent for my sn95 conversion

Really great quality Ball joints, worked great with my sn95 conversion, only thing is that they seem to be a little fatter than the stock ones, thus making the Spindle stay about 3/4th of an inch higher! I believe they are meant to be that way to fix Geometry!!

Overall I'm happy with them but had to have a set replaced under warranty, one of them ended up being noisy. Sucks that I had to do the repair over again, but after that everything thing is good and I'm happy with my purchase.
